PRMT5 is an epigenetic “synthetic lethality” target that has attracted much attention among drug hunters. The first generation of PRMT5 inhibitors was limited by systemic toxicities resulting in a cooling of industry interest, until the recent identification of tumor-specific inhibitors. These second-generation compounds target the MTA:PRMT5 complex in MTAP-deleted cancers—15% of all tumors—leading to a revival of the target. Read on to find out which companies are prevailing in the search for a first-in-class PRMT5 inhibitor and how their clinical compounds differentiate.

One of the key challenges in CNS projects is achieving sufficient unbound brain exposure to engage the target. To predict CNS exposure, scientists employ metrics like CNS MPO scores from Pfizer and Merck, Bayesian models, and methods for balancing physicochemical properties. However, these in silico metrics often fail to correlate well with experimental data. Schrödinger's team has discovered the energy of solvation (E-sol) metric, which accurately predicts Kp,uu and has been validated with CNS-penetrant DLK inhibitors.

In the aftermath of the thalidomide tragedy, the FDA advised excluding females in the childbearing age from early-stage clinical trials. However, this policy resulted in the prolonged underrepresentation of women in clinical research, limiting knowledge about how drugs affect genders differently. Recent policy changes, including the NIH's emphasis on considering sex as a biological variable, aim to reduce these disparities by promoting more diverse clinical trial participation. This article explores the current landscape of endometriosis therapies and how it relates to women’s healthcare.
